In Spring Boot, you can override default configurations in a jar by configuring properties in the application.properties or application.yml file of the application.<\/p>\n

    \n
  1. Create an application.properties or application.yml file and place it in the src\/main\/resources directory of the application.<\/li>\n
  2. In the configuration file, default configuration properties in the jar file can be overridden. For example, if the default configuration property in the jar file is server.port=8080 and you want to change it to server.port=8888, you can add the following content in the configuration file.<\/li>\n
  3. The port number for the server is 8888.<\/li>\n
  4. Maybe<\/li>\n
  5. server:
    \n port number: 8888<\/li>\n
  6. When running an application, Spring Boot will first read the properties in the application’s configuration file and override the default configurations in the jar. This allows the application to use the new configuration property values.<\/li>\n<\/ol>\n

    Note: If only some properties are configured in the application.properties or application.yml file, and not all properties in the jar are overridden, the application will use the default values of the properties that are not overridden.<\/p>\n","protected":false},"excerpt":{"rendered":"
